Which tissue type is a single layer of cube-shaped cells?

• A. Simple cuboidal epithelium
• B. Simple squamous epithelium
• C. Simple columnar epithelium
• D. Transitional epithelium

Answer: (A)

Single layer of cube-shaped cells is a hallmark of simple cuboidal epithelium. In this tissue, each cell is roughly boxlike with a central nucleus, arranged in a single plane to form a thin, uniform layer. It’s specialized for secretion and absorption and lines structures such as kidney tubules, ducts of glands, and the surface of the ovaries. This differs from simple squamous epithelium, which is a single layer of flat, diffusion-friendly cells; simple columnar epithelium, which has taller, column-like cells; and transitional epithelium, which is stratified and can change shape as it stretches.
